| Abstract: |
| Three different kinds of bead core for aircraft tire were presented，including the type A with the general structure and steel cord，the type B with the general structure and carbon fiber cord，and the type C with water drop structure and carbon fiber cord.The effect of the type of bead core on the tire performance during aircraft landing was investigated by finite element analysis and using Abaqus software.The results indicated that，compared with the tire having type A bead core，the maximum contact area pressure of the tire with type C bead core decreased by more than 50%，and the maximum equivalent stress was reduced by approximately two thirds.The contact area pressure and tire deformation at the landing center of the tires with different types of bead core were almost the same at the last step. |
